Similarly, the asphalt material layer of the second noise reduction layer 32 is also made of asphalt paint and/or asphalt sheet material. In a possible case, the layer of bituminous material of second noise-reducing layer 32 is made only of bituminous paint, which is applied to the outer wall of drum 2; in another possible case, the asphalt material layer of second noise reduction layer 32 is made of only asphalt sheet material, and the asphalt sheet material may be adhered to the outer wall of drum 2 by means of pasting or melting. Of course, the asphalt material layer may also be composed of asphalt paint and asphalt sheet, in which case, the asphalt paint may be coated on the outer wall of the drying cylinder 2 first, and then the asphalt sheet is adhered on the outer wall of the drying cylinder 2 coated with the asphalt paint, which are all within the protection scope of the present invention.
